Definition of JDM

It is a term used by companies in Japan that means Japanese domestic market.
As its name indicates, it refers to the car models, but especially their unique design parts, which were manufactured to be marketed in the Japanese market, this precisely increased the boom of vehicle modification or “tuning” in America.
The main characteristics of these models are in the reduction of weight of the car systems as much as possible.


  1. Japanese domestic market
  2. JDM


Japanese car manufacturing companies in the 1990s fought hard to produce the best gasoline cars in the market, making JDM specifications very successful.

JDM vehicles generally have different features and equipment in their systems than cars sold elsewhere.
The most addicted tuners of the engine, quickly realized this and began to import certain specific Japanese parts in order to have specifications equivalent to the cars of that market.

This was the beginning of the JDM revolution. The improvements – or “what they call tuning” – of the performance of the vehicles are then made visible with these components in order to get the most out of your vehicle.
Thus, and within the automotive import universe, the term generally refers to Japanese vehicles of the same brand, of course, but especially to the parts of its own factory and design, so that they can be adjusted to other automobiles.


Since the late 70’s there were limitations of JDM cars by a pact made between the manufacturers to 280 horsepower in 1988 and a maximum speed of 180 or 190 km / h. This was mainly due to safety concerns.

This JDM styling began to become much more common on the streets of North America and both garages and specialty companies made a quick resurgence. The “Fast & Furious” franchise was not a fluke, it emerged in that context.

It is possible that vehicles built under the JDM distinction have stiffer suspensions and throttle response is different for different markets.
Several of the JDM sports cars have speedometers that only go up to 180 km/h, incorporating a speed limiter, although the car has the capacity to reach higher speeds.
